This comment is long past editing deadline but since most replies seem to have misinterpreted me, I must have worded it very badly, so will clarify: Basic tutorials for Python newbies use wsgi. Copying & pasting from SO without understanding the code you're copying will inadvertently net you a wsgi setup. FastAPI requires wsgi. I wasn't stating that everyone deploying Python has a depth of knowledge of wsgi - I was enquiring as to whether there's some other alternative system people pervasively use for Python web apps, as I assumed everyone was on wsgi (whether they're aware of it or not). TL;DR: by "learning what wsgi is" I just meant "deploying it" not "understanding it in depth"
